sami, i think yes it is possible you've ov. I've got a zita west book on ttc and there was a case study in there of a woman who after 9 months of ttc still wasn't pg but always had sex around day 14 because as a rule thats when most women ov. After going to see her, she was told how to check cm and when she noticed cm as her period was finishing, she realised she might be ov. she fell pg that month and managed to concieve on 6dpo!
